If you can't figure this out with an equation, try process of elimination.

14 @ 6 = 84
19 @ 15 = 285
285 + 84 = 369
Nope, the first one is not correct.

If you need an equation.
let A = # adults
and C = # children
====================
number of attendees = 33; therefore,
A + C = 33
And cost of tickets was total of $360; therefore,
15*A + 6*C = 360
Solve the two equatins for A and C.
